University administrators have made difficult choices in response to the changing policy context for the use of affirmative action in admissions. This paper synthesizes the empirical literature on affirmative action and evaluates the efficacy of alternative strategies, including top-percent programs, class-based affirmative action, and targeted recruiting. The analyses offer several findings of interest to officials who direct such programs: (1) Affirmative action preferences given by top-tier universities have been large; (2) affirmative action leads minorities to enroll in higher-quality institutions; and (3) affirmative action has mostly positive effects on minority students later in life. The evidence shows a decline in minorities' relative share of enrollment at flagship public universities after affirmative action was eliminated in several states, and the alternative strategies used by these universities have not offset these declines. 相似文献

Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health. 相似文献

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That, to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed." These words from the Preamble to the Declaration of Independence, proclaimed a conviction and announced a challenge for our newly formed nation. Today, they either stir the American heart with pride or generate nostalgia for a time when any truth was self-evident and the right to life was deemed inalienable. 相似文献

The Targeted Jobs Tax Credit (TJTC) is a representative redistributive incentive. Initially, proponents saw TJTC as an elegant program, efficiently promoting labor market behavior that would solve the employment problems of many disadvantaged job seekers. However, interest groups distorted the credit into a windfall for businesses that hire large numbers of low wage workers. The policy theories incorporated into TJTC, which emphasized continual program reform and minimized program management by public administrators, provided a setting conducive to interest group distortion. Because few representatives of the disadvantaged participated in the oversight process, special interests undermined TJTC being reformed through empirical evaluation. This experience indicates that without major changes in the policy process, narrowly targeted rzdistributive policies should be avoided. 相似文献

The "corporate liberal" regime that held together in America from the end of World War I1 to the 1960s was marked by broad agreement on ideology, public policy and a stable ruling coalition centered in the Democratic Party. This regime unraveled in the late 1960s and 1970s with the relative decline in American military and economic hegemony and the rise of a "left liberal insurgency". Key corporate liberal intellectuals and constituencies migrated to the Republican Party under Reagan. Reaganism will not sustain itself because its coalition partners are too disparate, its failure to transform the Republicans into a majority party, a lack of consensus on many issues, and the continued decline of the U.S. in the international economy. Corporate liberalism will find itself migrating to a revitalized Democratic Party, under a centrist leadership favoring fiscal responsibility, government-corporate partnerships, and a more efficient military. 相似文献

By 1992, the party of the majority, the Democratic Party, will have been out of power for twenty years of a twenty-four year span. Since 1968, numerous reforms in the presidential nominating process have been considered and adopted by the Democrats. These reforms have had the effect of opening the nominating process to rank-and-file Democrats through state primaries and participatory caucuses. While the reforms achieve this purpose, the end result is a mixed system that has been described as a disjointed hodgepodge of rules.
This article presents ten criteria of a sound nomination system. Then a panel of researchers and practitioners weighs seven options for further reform against the ten criteria. Several policy options are considered by the panel as improvements over the current presidential nomination system. 相似文献

This study investigated the effects of family structure (parents together or not) and parental discord (ratings of the happiness of the marriage of biological parents) on the self-esteem of 199 female undergraduates. Family structure and happiness ratings were substantially related, with those separated rated as less happy. Self-esteem was significantly related to parental happiness, even with family structure controlled, but not to family structure with parental happiness controlled. With the sample divided into three groups (happy-together, unhappy-together, and separated) ANOVA showed a significant effect for group, with the unhappy-together group showing significantly lower self-esteem than the happy-together group, and the separated group intermediate. Parental discord thus appears to lower the selfesteem of daughters, whereas separation of parents does not. These findings support Heatherington's idea that children may be better off in a stable family where parents are divorced than in an intact family with much parental discord.Thanks are expressed to Susan Stevenson Cowles for her contributions to all stages of the study, and to Judith Fidati, Anita Katz, and Susanne Long for their assistance in the scoring and statistical analyses. The author is also grateful to Andrew Cherlin, Edmund Henderson, and Ruth C. Wylie for their helpful suggestions.Barbara H. Long is Professor Emeritus at Goucher College, where she has taught for 20 years. She is a social psychologist, having received her Ph.D. from the University of Delaware and has, at present, research interests in the attitudes of young women towards marriage and career. 相似文献
